(54) СПОСОБ КОНТРОЛЯ ТЕМПЕРАТУРЫ МЕТАЛЛА В КОНВЕРТОРЕ(54) METHOD OF CONTROL OF METAL TEMPERATURE IN THE CONVERTER
прерывного измерени углёродсодержащих газов.discontinuous measurement of carbon-containing gases.
Сущность предлагаемого способа состоит в следующем. Перед началом продувки по статическому алгоритму рассчитываетс врем продувки (или суммарное количество кислорода). По достижении 2/3 от общей продолжительности продувки (или суммарного количества кислорода) в конвертор вводитс заранее приготовленна эталонна присадка карбонатсодержащего материала, например известн ка. Под действием температуры ванны присадка известн ка разлагаетс с выделением углекислого газа, что фиксируетс на кривой непрерывного измерени углёродсодержащих газов. Определив врем разложени присадки известн ка, которое равно времени от момента дачи присадки до выхода кривой измерени на максимальную величину, рассчитывают температуру металла по зависимости ( 1 ). Это расчетное значение температуры может быть использовано как базовое измерение температуры жидкой стали дл получени заданной температуры в конце продувки.The essence of the proposed method consists in the following. Before the start of the purge by the static algorithm, the purge time (or the total amount of oxygen) is calculated. Upon reaching 2/3 of the total duration of the purge (or the total amount of oxygen), a previously prepared standard additive of carbonate-containing material, such as limestone, is introduced into the converter. Under the action of the bath temperature, the limestone decomposes with carbon dioxide evolution, which is fixed on the curve of continuous measurement of carbon-containing gases. Having determined the time of decomposition of the limestone additive, which is equal to the time from the moment of the addition of the additive to the output of the measurement curve at the maximum value, the temperature of the metal is calculated from dependence (1). This calculated temperature value can be used as a basic measurement of the temperature of the molten steel to obtain the set temperature at the end of the purge.
Технико-экономическа эффективность от применени предлагаемого способа состоит в том, что он позвол ет контролировать температуру жидкой стали в конверторе без прекращени продувки и без использовани вспомогательной фурмы («зонда), достига при этом точности измерени температуры в i15°С.The technical and economic efficiency of applying the proposed method is that it allows you to control the temperature of the liquid steel in the converter without stopping the purge and without using an auxiliary tuyere ("probe") while achieving an accuracy of measuring i15 ° C.
